'This invention relates to lubricating devices. 1

One object of the invention is to provide an im roved journal lubricating device es- 6 pecial y adapted for use in connection with locomotive driving boxes, said device including a detachable grease cellar provided with a central compartment designed for the de; tachable reception of automatically 0 erable m grease distributing means, together with side extensions adapte to fit into the driving box and so arranged as to provide grease pockets concentrically disposed with reference to said journal at either side of said central l6 compartment, andalso providin air circulating passages about the 'ourna to cool the same when said grease cel ar is in operative position in the driving box. I

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings, Fig. 1 is an end elevation of a grease cellar embodying my invention, showing the same applied to a dr1ving box. Fig. 2is a vertical, sectional view of the ease cellar substantially on the line 22 0% sectional view ofthe grease cellar tially on the line.3--3 of Fig. 2. j

Referring to Fig. 1 of the drawings, a driving box and journal of the usual type are illustrated, the driving box be ng provided with spaced jaws 10-10 defining a U-shaped opening adaptedfor the reception substan preferably madeup in theform of a casting having BrbOttOIII wall 13, verticalside walls being suchthat loosening of the screws permits dropping ofthe plate 16, which can be again elevated and secured by the screws in a position over theend of the central compartment defined by the Side walls14-14,' and end wall 15. The topedges of the end F ig. l, and Fig. 3 is a vertical,

" of the journal 11, the usual brass or liner 14-44, one integral end wall 15,and amov-l 1926. Serial No. 109,229.

walls 15 and 16 are arranged concentrically with reference to the curvature of the journal 1 1, and whenthe cellar is in operative posltlon the top edges of said end walls are slightly spaced from said journal. The central chamber is adapted for the detachable reception of an automatic dispensing device, the side walls 14-14 being provided with oifsets 19-19 for cooperation therewith in a manner hereinafter described. Disposed in the central compartment is an arcuate plate 20 providedwithvertically disposed flanges 21 -21 which fit into the ofi'sets 19-19 of the side walls and cooperate with said oifsets to limit the downward movement of the plate 20. i The plate 20 is adapted to have its arcuate face bear against the journal 11, .said arcuate portionbeing provided with a plurality of openings 22 through which lubricant may be passed to the journal. Mounted for cooperation with the plate 20 is a follower plate 23 on which a grease cake 24 rests, the follower plate 23 being provided with spring seats 25-25on its under-surface, which are in alineinent with springs 26=26 which bear against the follower plate 23 to normally force the same in an upward direction. Grease gauges 27-27 are secured at their upper ends to. the follower plate23 and project through open.- ings 28 in the bottom. wall 13 of the reuse cellar so that anyone examining the ce 1' to ascertainwhether ornotit needs a new cake of grease can easilydetermine this by inspec+ tion ofthegauge rods27-27s r .The central chambered rtion of the grease cellar is of relatively small extent when compared to the distance betweenthe jaws 10-+10 of the drivingbox, andthe re mainder of the space between thejaws and 95 the central'chambered portion is taken up by an arrangementwhich provides. for ad ditional grease pockets disposed about the journal and for circulatory air passages about I the journal, while at the samextime L00 permitting mice fit of the cellar between i the jaws 10-40 of thedriving box. and without interfering with the me independent removal, replacementand operation of the automatic rease dispensingdevice. v

Preferably formed integrall with upper portions of the side Wallis 14---14,san'd somewhat below the top edges thereof, at .eachside of the .centralxcompartment, are curved walls 29-29, which adjacenttheir 1 10 outer extremities are arranged vertically as indicated at 30'30, and each of said walls terminates in a horizontally disposed flan e- 31, the portions 30 being of a width su stantiall corresponding to the distance between tie opposite engagin faces of the jaws 1010. At each end 0 the cellar, the walls 2929, and walls 3030 merge into the end walls 32-32, the top edges of said latter walls being concentrically disposed with reference to the journal 10 and nor mally spaced therefrom as shown, this construction providing a shallow grease collecting pocket at each side of the central chamber, which grease pockets are concentrically arranged with reference to the journal 11. i

Preferably formed at the lower four corners of the walls 1{1-14 are lateral extensions or lugs 33-33, said extensions providing base portions having their outer faces spaced apart a distance to fit snugly between the inner faces of the jaws 10-10 of the driving box, the portions of the cellar between the grease pockets and the extensions 33 being cut out at each side of the cellar as indicated at 3434, so that the cellar when in position in the driving box will have air passages which extend closely adjacent to the central compartment of the cellar and are disposed about "said concentric shallow grease pockets to provide for circulation of air and cooling of the journal. \Vebs 85-35 are extended laterally to each side of the central chamber walls lat-14 to increase the strength of the device. The cellar is held in position between the jaws ofthedriving box b means of suitable pins indicated at '36,11w ich project through the extensions upon the lower portion of the cellar'and through the bores provided in the lower ends of the jaws 1010 of the driving box.

In practice the grease cake 24 is pressed upwardly by the spring follower plate 23, holdin grease ca 20 in contact with the journa, the revo vin journal forming a suction whichdraws t e needed amount of grease throughthe perforations in the plate 20, and this grease keeps the journal constantly lubricated. When the hasibeen consumed, this fact is indicated by the position of the gauges 27-27, and by loosening the screws 1818, the plate 16 may be dropped so as to give access to the central compartment, and the plate 20 may beslid longitudinally out of the central compartment and-a new grease cake inserted inposition, after which the plate 16 may be elevated and the screws 18-18 again tightened. When it is desired 7 to remove the journal 11 from the box, the grease cellar may be readily detached by withdrawing the bolts or pins 36 which permits the grease cellar to be withdrawn from the driving box.

The concentrically disposed shallow side ease cake vfreely both vertically and longitudinally in close proximity to the journal and so cool the same, the arrangement being 'such'that foreign material is efiectively excluded while permitting the desirable circulation of air about the parts. a

While I have herein shown and described what I now consider the preferred manner of carrying out the invention, the same is merely illustrative, and I contemplate all changes and modifications that come within the scope of the claims appended hereto."
